Special Issue Information

Dear Colleagues,

Organic peracids, such as performic and peracetic acids, are widely used in industrial applications requiring disinfection, sterilization, or a high oxidation potential. Currently, the largest user segments of these chemicals are the food, healthcare, water treatment, production of fine chemicals, and pulp and paper industries. Even though both performic acid and peracetic acid were synthesized for the first time over 100 years ago, active research on their properties and potential uses has continued up to this day. An important driver in their use is the low tendency for the formation of disinfection by-products—a property not exhibited by many of the competing disinfectants and oxidizers.

The title of this Special Issue is “Organic Peracids in Novel Environmental and Public Health Applications”. The scope of this issue includes all organic peracids (not just performic and peracetic acids) and all of their environmental and health-related applications. Potential topics include (but are not limited to):

  • Research on synthesis or analytical methods of organic peracids;
  • Disinfection/sterilization of surfaces (for instance, in healthcare or the food industry);
  • Novel uses in water and wastewater treatment (such as advanced oxidation processes, ballast water treatment, and potable water disinfection); and
  • Characterization and modeling of reactions of organic peracids.

In recent years, peracetic acid (PAA) has gained a lot of attention as an alternative disinfectant to chlorine-based disinfectants in the water industry. Commercial PAA solutions contain both PAA and hydrogen peroxide (HP), and the degradation of HP is slower than PAA when it is used for disinfection. All previous toxicity studies have been based on commercial PAA, and variance in toxicity values have been observed due to different PAA:HP ratios. In this study, the ecotoxicity of pure PAA was studied, eliminating HP from the commercial PAA mixture using potassium permanganate. Ecotoxicity data were obtained by conducting a battery of ecotoxicity tests: bioassays using Vibrio fischeri (V. fischeri), Daphnia magna (D. magna), and Pseudokirchneriella subcapitata (P. subcapitata). The effect concentration (EC50) of pure PAA was 0.84 (a 95% confidence interval of 0.78–0.91) mg/L for V. fischeri and 2.46 (2.35–2.58) mg/L for P. subcapitata, whereas the lethal concentration (LC50) was 0.74 (0.55–0.91) mg/L for D. magna. Compared to this, our previous study found that the EC50 values of commercial PAA towards V. fischeri and P. subcapitata were 0.42 (0.41–0.44) and 1.38 (0.96–1.99) mg/L, respectively, which were lower than pure PAA, whilst the LC50 for D. magna was 0.78 (0.58–0.95) mg/L. These results showed that pure PAA was less toxic to the most commonly used aquatic species for toxicity tests compared to commercial PAA, except for D. magna. Full article

Peracetic acid (PAA) water solutions is applied for disinfection of industry systems, food products and non-potable water. Commercially available peracetic acid is always supplied mixed with hydrogen peroxide (H2O2). H2O2 degrade slower than the peracetic acid which creates a need to quantify both peroxides separately to gauge the disinfection power of the solution and the residuals. Two combinations of colorimetric reactions are presented that allows simultaneous quantification at the mg·L−1 level used in disinfection liquids and water disinfection. The first dichromic reaction use titanium oxide oxalate (TiO-Ox) which only react with H2O2 followed by addition of N,N-diethyl-p-phenylenediamine with iodide (DPD/I−) and the concentrations are read by simultaneously measuring the absorbance at 400 and 515 nm. Limit of quantification (LOQ) and maximal concentration determined was 4.6 µg·L−1 and 2.5 mg·L−1 for PAA and 9.1 µg·L−1 and 5 mg·L−1 for H2O2. The two color reactions didn’t interfere with each other when the reagent addition was consecutive. Another combination of colorimetric reaction also used where TiO-Ox was used to first measure H2O2 at 400 nm, before addition of 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS)) and reading the absorbance at 405 nm. ABTS changes the absorbance at 405 nm necessitating the two measurements be done separately. LOQ and maximal concentration determined using ABTS colorimetric assay was 42.5 µg·L−1 and 30 mg·L−1 for PAA and for titanium oxide oxalate colorimetric assay was 12.7 µg·L−1 and 75 mg·L−1 for H2O2. Both methods tested satisfactory in typical water samples (Tap, sea, lake, and biological treated sewage) spiked with peracetic acid and H2O2, separately. Full article
